Auxiliary contact CA5-22E 1SBN010040R1022

Universal ABB CA5-22E auxiliary contact block – a reliable extension of capabilities

The CA5-22E auxiliary contact block is a component dedicated to expanding the functionality of circuit breakers and contactors. It allows adding additional auxiliary contacts, which is crucial in applications requiring complex control logic or circuit status signaling. Front-mounted, it provides convenient installation and configuration.

Design and application

CA5-22E is characterized by top mounting, which facilitates its integration with existing installations. Made of high-quality materials, it guarantees durability and reliability even in demanding working conditions. Electrical connection is realized by means of solid screw terminals, ensuring a secure and safe connection of wires. This block finds application in a wide range of industrial and construction applications where an increased number of auxiliary contacts are needed for control, signaling or protection purposes.

Key features and benefits

• Versatility: Availability of two normally open (2NO) and two normally closed (2NC) contacts allows for flexible adaptation to specific application needs.
• Secure connections: Screw connections guarantee stable and reliable connection of wires, minimizing the risk of circuit interruptions.
• Easy installation: Front mounting and the design allowing top mounting significantly simplify the installation process.
• Compliance with standards: The product meets stringent safety and quality standards, ensuring safe and reliable operation.
• For AC-15: Rated operating current of 4A for AC-15 means that the contact block is adapted to control circuits with moderate power. This is important when designing control circuits for motors, heaters or other loads.
• No fault signaling contacts: The lack of dedicated fault signaling contacts simplifies the design and reduces costs in applications where this is not required.

The CA5-22E block is a solid choice for both professional installers looking for a reliable component for their projects, and for end-users wanting to expand the functionality of existing electrical installations.
